Liam Neeson had everybody talking earlier this week when he was photographed in New York looking unusually thin and frail.

His appearance was all the more shocking considering that the 63-year-old actor has made a career playing action heroes on the big screen.

Naturally, we had to make him the subject of our Friday face morph so we could track the actor's journey from Irish heartthrob to Hollywood superstar.

Seeing as how Taken 3 was released earlier this year and he has two action films currently in post-production, the star must be in reasonably good health, so perhaps he's slimming down for a new role?

The evolution of Demi Moore's face

2 of 17

Demi Moore has had a pretty terrible week, following the drowning death of a man at her house while she was overseas, so we understand she may not be looking her best. But recent paparazzi photos show the 52-year-old actor looking more worn out than we've ever seen her.

Naturally, when we see any star out in public with a drastically changed appearance, a face morph isn't far behind. This week it's Demi's turn.

She has always denied having plastic surgery, and even though there have been some suspicious changes to her face over the decades, maybe she's just blessed with amazing genes.

The evolution of Meg Ryan's face

3 of 17

Meg Ryan has made her first public appearance in over a year, attending multiple fashion shows in Paris. However, despite her fabulous outfits, it was her face that got everybody talking.

The 53-year-old has never confirmed whether or not she has gone under the knife, but her smooth forehead, full lips and pinched expression are pretty telling.

Because we would never speculate about a celebrity's appearance without hard evidence, we searched the archives for photos of Meg and put together a face morph…for science.

The evolution of Kylie Jenner's face

4 of 17

Of all the Kardashian-Jenner sisters, Kylie's appearance has changed the most – no mean feat when your older sister is Kim.

Earlier this week two US plastic surgeons claimed that the 17-year-old has had more than $50,000 worth of work done, while Kylie insists that it’s just make-up.

Check out our face morph video and decide for yourself. Sure, all our faces change as we go through puberty, but we don't remember our lips getting quite that big as we got older.

The evolution of Kim Kardashian West's face

5 of 17

It's true! TheFIX are hands-up guilty of obsessing over 34-year-old Kim Kardashian's ever-changing face since she first stepped onto the scene back in 2007.

Is it surgery? Is it a case of Benjamin Button meets reality TV queen? Is it just makeup? These are the questions that plague us regularly.

The evolution of Kyle Sandiland's face

6 of 17

Kyle Sandilands turns 43 today! Happy birthday. But how much has the shock jock changed over the years?

Lets take a little look at him morph from sweet-faced teen to the man we know today. There's one thing which hasn't changed...that cheeky grin.

The evolution of Nicole Kidman's face

7 of 17

Nicole Kidman has admitted to using Botox in the past but always stopped short of confirming whether or not she has undergone any cosmetic surgical procedures.

Of course, that doesn't stop everybody from speculating, and this week saw fresh claims from an Aussie magazine that the 48-year-old has gone under the knife.

So in an attempt to get to the truth of the matter (and relive the joy that was Nicole's 80s hair), we decided to make her the subject of our Friday face morph.

The verdict? Well, she's definitely looking a little more pinched these days than she did 20 years ago, but we'll let you decide for yourself.

The evolution of Jennifer Aniston's face

8 of 17

It's hard to believe Jennifer Aniston has been in our lives for more than 20 years.

In the past, Jen has admitted to having a nose job to correct a deviated septum. She also loves a bit of laser therapy, but draws the line at Botox.

Whatever she’s doing, it’s working because at 45, Jen is looking as stunning as ever… talk about coming into her prime!

The evolution of Ricky Martin's face

9 of 17

The Voice returns to our screens this Sunday and to celebrate we've taken an in-depth look at one of our favourite coaches – Ricky Martin!

Yep, Ricky is getting the face morph treatment, from a 13-year-old heartthrob with 80s boy band Menudo to some horrifying haircuts as a solo artists in the 90s.

Warning: Mullets will be witnessed.

Thankfully the 43-year-old has now finally found a hairstyle that works for him and he is looking better than ever.

The evolution of Angelina Jolie's face

10 of 17

It's Angelina Jolie's 40th birthday and to celebrate, we've trawled through the archives to see how she's changed from Hollywood offspring to drug-addled rebel to the wholesome human-rights advocate of today.

And while she's always been a stunner, we're calling it…she's got better with age.

So, what's her secret? Good genes, a fulfilling family life or subtle surgery? Take your guess, FIXies.

The evolution of Johnny Depp's face

11 of 17

Johnny Depp has been in the news for all the wrong reasons lately.

After he went missing from the set of the new Pirates of the Caribbean film, he returned to Australia in spectacular fashion when he smuggled his pet dogs into the country.

The fugitive pooches have since returned home, but the Australian government is still threatening to charge Depp with breaching biosecurity laws.

To celebrate his return to the spotlight, we've done what we do best – trawled through the archives and put together a mesmerising face morph. His face may have changed, but that chiselled jawline has stayed exactly the same.

The evolution of Hugh Jackman's face

12 of 17

Hugh Jackman has been on our radar in a big way this week. He freaked us out in the trailer for his upcoming film Pan, then he had us laughing as he schooled Jimmy Fallon on how to eat Vegemite.

To celebrate the 46-year-old heartthrob, we decided to take a trip down memory lane and see how he has changed over the years (it was also a good excuse to stare fondly at his face).

Hugh has had a few questionable haircuts through the years, but overall he's definitely gotten better with age.

The evolution of Mariah Carey's face

13 of 17

The cover for Mariah Carey's new album dropped recently and the heavy-handed photoshopping raised a few eyebrows here at TheFIX.

So being the shrewd investigative journalists that we are (ahem), we decided to trawl through the archives and remind ourselves of how Mimi has changed over the years.

The 46-year-old still looks stunning after 25 years in the spotlight, though the jury is still out on whether or not she's had work done. Either way, she needs to lay off the photoshop.

The evolution of Kelly Osbourne's face

14 of 17

Kelly Osbourne has been in the public eye her entire life – which means that every ill-advised haircut, terrible make-up job and kilogram gained or lost has been well documented. Naturally, this makes her the perfect choice for this week's Friday face morph. Remember when she attempted a career as a pop-punk singer?

Oh well, at least the 30-year-old has got it together now. Check out the video to see how the surly teenager became the stunning fashionista we know today.

The evolution of Bruce Jenner's face

15 of 17

If change is good, Bruce Jenner, 65, must be having a great life.

The man who won the Olympic decathlon gold medal nearly 40 years ago looks very little like the man who may now be best known as Kim Kardashian's stepfather.

The evolution of Madonna's face

16 of 17

The 56-year-old pop star is often criticised for quite obviously going under the knife, but our video shows Madonna getting better and better with age.

Hello, she's a fox.

The evolution of Bruce Willis' face

17 of 17

To celebrate Bruce Willis' 60th birthday, TheFIX took an in-depth look at how the actor has changed over the years.

The Hollywood legend has been rocking the trademark bald head for most of his career, but we couldn’t help but notice some subtle variations in his face throughout the years… and not the regular aging kind.
